(i) F lives on an even-numbered flat on the even-numbered floor. (ii) D and I live on even-numbered flats. I lives immediately below F. F lives at flat no.  2 on floor no. 2. D and I lives at flat no. 2 on floor no. 3 and 1 respectively. (iii) G lives immediately below C. (iv) E lives on an odd-numbered floor. E lives on one of the same flat above G. From these statements, there will be two cases: If E lives at flat no. 1 of floor no. 3 then G lives at flat no. 1 of floor no. 1. If E lives at flat no. 3 of floor no. 3 then G lives at flat no. 3 of floor no. 1. C lives at either flat no. 1 or 3 of floor no. 2. C lives on the same floor with J. So, A lives either at flat no. 1 or 3 of floor no. 2. B lives immediately below J. So, B lives either at flat no. 1 or 3 of floor no. 1. A lives on flat -1. So, case 1 will get discarded. The persons who like Lenovo, Apple, and Acer live in the odd-numbered floors on the odd-numbered flat. The person who likes Asus lives immediately above the one who likes Apple.
